Text Generation AI
About: ChatGPT is a chatbot and virtual assistant developed by OpenAI and launched on November 30, 2022. Based on large language models (LLMs), it enables users to refine and steer a conversation towards a desired length, format, style, level of detail, and language.
ChatGPT is built on OpenAI's proprietary series of generative pre-trained transformer (GPT) models and is fine-tuned for conversational applications using a combination of supervised learning and reinforcement learning from human feedback.
ChatGPT is credited with starting the AI boom, which has led to ongoing rapid investment in and public attention to the field of artificial intelligence (AI).[3] By January 2023, it had become what was then the fastest-growing consumer software application in history, gaining over 100 million users and contributing to the growth of OpenAI's current valuation of $86 billion.
Cost: ChatGPT was released as a freely available research preview, but OpenAI now operates the service on a "freemium" model due to its popularity. Users on its free tier can access GPT-4o and GPT-3.5. The ChatGPT subscriptions "Plus", "Team" and "Enterprise" provide additional features such as DALL-E 3 image generation and increased GPT-4o usage limit.
ClaudeAbout: Claude is a family of large language models developed by Anthropic.The first model was released in March 2023. Claude 3, released in March 2024, can also analyze images. The Claude 3 family includes three state-of-the-art models in ascending order of capability: Haiku, Sonnet, and Opus.
Cost: Limited-use access using Claude 3.5 Sonnet is free of charge, but requires both an e-mail address and a cellphone number. A paid plan is also offered for more usage and access to all Claude 3 models. On May 1, 2024, Anthropic announced the Claude Team plan, its first enterprise offering for Claude, and a Claude iOS app.
GeminiAbout: Gemini, formerly known as Bard, is a generative artificial intelligence chatbot developed by Google. Based on the large language model (LLM) of the same name and developed as a direct response to the meteoric rise of OpenAI's ChatGPT, it was launched in a limited capacity in March 2023 before expanding to other countries in May.
Cost: Gemini has a limited free option, or users can opt for Gemini Advanced, which includes integration with Google Workspace and cloud storage with Google One.
MetaAIAbout: Meta AI is an American company owned by Meta (formerly Facebook) that develops artificial intelligence and augmented and artificial reality technologies. Meta AI deems itself an academic research laboratory, focused on generating knowledge for the AI community, and should not be confused with Meta's Applied Machine Learning (AML) team, which focuses on the practical applications of its products.
Cost: As of July 2024, MetaAI is free to use without any paid subscription.
Concerns: Since May 2024, the Meta AI chatbot has summarized news from various outlets without linking directly to original articles, including in Canada, where news links are banned on its platforms. This use of news content without compensation has raised ethical and legal concerns, especially as Meta continues to reduce news visibility on its platforms
CopilotAbout: Microsoft Copilot is a generative artificial intelligence chatbot developed by Microsoft. Based on a large language model, it was launched in February 2023 as Microsoft's primary replacement for the discontinued Cortana. The service was originally introduced under the name Bing Chat. Copilot utilizes the Microsoft Prometheus model, built upon OpenAI's GPT-4 foundational large language model, which in turn has been fine-tuned using both supervised and reinforcement learning techniques.
in December 2023, Copilot was added without payment to many Windows 11 installations. Later that month, a standalone Microsoft Copilot app was released.
Microsoft Copilot in Windows supports the use of voice commands. By default, it is accessible via the Windows taskbar. Copilot in Windows can provide information on a website currently being browsed by a user in Microsoft Edge. Copilot can also be used to rewrite and generate text based on user prompts in Microsoft 365 services including Microsoft Word, Excel, PowerPoint, Outlook, and Teams.
Cost: Microsoft operates Copilot on a freemium model. Users on its free tier can access most features, while priority access to newer features, including custom chatbot creation, is provided to paid subscribers under the "Microsoft Copilot Pro" paid subscription service. Several default chatbots are available in the free version of Microsoft Copilot, including the standard Copilot chatbot as well as Microsoft Designer, which is oriented towards using its Image Creator to generate images based on text prompts.
PerplexityAbout: Perplexity AI is an AI chatbot-powered research and conversational search engine that answers queries using natural language predictive text. Launched in 2022, Perplexity generates answers using sources from the web and cites links within the text response.
Who made it? Perplexity was founded in 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho and Andy Konwinski, engineers with backgrounds in back-end systems, AI and machine learning. Yarats, the CTO, was an AI research scientist at Meta, while Srinivas, the CEO, worked at OpenAI as an AI researcher. Ho, the Chief Strategy Officer, worked as an engineer at Quora, then as a quantitative trader on Wall Street, and Konwinski was among the founding team at Databricks.
Cost: Perplexity works on a "freemium" model; the free product uses the company's standalone large language model (LLM) that incorporates natural language processing (NLP) capabilities, while the paid version Perplexity Pro has access to GPT-4, Claude 3.5, Mistral Large, Llama 3 and an Experimental Perplexity Model.
Concerns: In June 2024, Forbes publicly criticized Perplexity for their use of Forbes' content. According to Forbes, Perplexity published a story which was largely copied from a proprietary Forbes article, without mentioning or prominently citing Forbes. In response, Srinivas said that the feature had some "rough edges" and accepted feedback, but maintained that Perplexity only "aggregates" rather than plagiarizes information.
Separate investigations by the magazine Wired and web developer Robb Knight found that Perplexity does not respect the robots.txt standard, which allows websites to stop web crawlers from scraping content, reportedly despite Perplexity claiming the opposite. Perplexity also lists the IP address ranges and user agent strings of their web crawlers publicly, but according to Wired and Robb Knight, they use undisclosed IP addresses and spoofed user agent strings when ignoring robots.txt.
MistralAbout: Mistral AI is a French company specializing in artificial intelligence (AI) products. The company focuses on producing open-source large language models, emphasizing the foundational importance of free and open-source software, and positioning itself as an alternative to proprietary models.
Who made it? Founded in April 2023 by Arthur Mensch, Guillaume Lample and Timothée Lacroix, the company has quickly risen to prominence in the AI sector. Before co-founding Mistral AI, Arthur Mensch worked at Google DeepMind which is Google's artificial intelligence laboratory, while Guillaume Lample and Timothée Lacroix worked at Meta Platforms.
